Answer: blue is 25% chance
Step-by-step explanation:
8+11+5+3+9=36 then blue would be 9/36 of all the yarn and 9/36 converted into a percentage is 25%
The diameter of the circle is 5.4 cm. The shaded area is 180 degrees, which is 1/2 of the circle.
Calculate the area of the full circle and divide by 2.
Area = PI x r^2
r = 5.4/2 = 2.7
Area = 3.14 x 2.7^2 = 22.90
Area of shaded part: 22.90 / 2 = 11.45 cm^2.
The answer is A.
Answer: -20 1/12
Step-by-step explanation:
-8 + -11 = -19
-3/4 + -1/3 = -1 and 1/12
so -19 + -1 and 1/12 = -20 and 1/12
F ( x ) = 7 x + 2
y = 7 x + 2
- 7 x = - y + 2 /*(-1)
7 x = y - 2 / : 7
x = y/7 - 2/7 = ( y - 2 ) / 7
The inverse of the function is:
f^(-1) ( x ) = ( x - 2 ) /7
